Abstract (en)
[origin: EP0469630A2] A process for preparing a semiconductor member comprises the steps of: forming a member having a non-porous monocrystalline semiconductor region on a porous monocrystalline semiconductor region, bonding the surface of a member of which the surface is constituted of an insulating substance onto the surface of the non-porous monocrystalline semiconductor region, and then removing the porous monocrystalline semiconductor region by etching. <IMAGE>
